- ПубликацияТолько метаданныеCritical view at quality evaluation systems of stochastic algorithms for information security(2019) Chugunkov, V. I.; Chuzunkov, I. V.; Dyumin, A. A.; Maksutov, A. A.; Liman, D. A.; Чугунков, Илья Владимирович; Дюмин, Александр Александрович; Максутов, Артем Артурович© 2017 IEEE. This paper is devoted to pseudo-random number (PRN) generator testing. The main evaluation systems of statistical properties of pseudo-random sequences formed by PRN generator are considered in the scope of this work. Weaknesses of such systems and ways of tests bypassing were revealed. The example of improving statistical properties of generator through adding statistical randomizer is given. We also propose approach to increasing efficiency of evaluation systems of statistical security of stochastic algorithms based on the usage of artificial neural networks.

A.; Чугунков, Илья Владимирович; Ядыкин, Игорь Михайлович© 2019 IEEE.The article is devoted to the improvement of stochastic transformation blocks (R-blocks). The principles of R- blocks construction are considered. We review the examples of R- blocks using in the cryptographic algorithms. The structure of two-dimensional stochastic transformation block is proposed, as well as the method for construction of multidimensional R- blocks. The using of improved R-blocks for construction of multidimensional algorithms is proposed.

I.; Riakhovskaia, I. S.; Tsyganov, V. S.; Чугунков, Илья Владимирович© 2019 IEEE.The article is devoted to the issues of building and quality assessment of replacement block or S-box, which is one of the main blocks of cryptographic transformation. The principles of S-box designing are considered, examples of their using in modern block ciphers are given. The issues of assessing the statistical safety of S-boxes, in particular, the criteria used for the analysis of S-blocks are investigated. The structure of the program system for the study of the statistical properties of S-boxes is proposed. The results of the S-boxes analysis for the main modern cryptographic algorithms are given. Assumptions about the possibility of mathematical apparatus using for the statistical properties of S-boxes analyzing are made.
- ПубликацияТолько метаданныеMethod for improving the statistical properties of pseudo-random number generators(2019) Chugunkov, V. I.; Chugunkov, I. V.; Gulyaev, V. A.; Baranova, E. A.; Чугунков, Илья Владимирович© 2019 IEEE The article is devoted to the issues of increasing the statistical safety of pseudo-random number generators by equalizing the properties of the generated sequences. The traditional generator structure assumes two stages: the first provides good statistical properties and a long period of the formed sequence, the second is responsible for unpredictability and cryptographic resistance. In this case, the second stage can lead to deterioration in the statistical properties of the sequence formed by the generator. An approach based on adding to the traditional two-stage generators architecture of third-stage is considered. A variant of the third stage construction is proposed. The possibilities of applying the proposed approach to improve the statistical properties of modern ciphers are described. The results of statistical properties researches of the generators with implemented third stage are given.
- ПубликацияТолько метаданныеGenerators with the given distribution law(2019) Chugunkov, V. I.; Chugunkov, I. V.; Riakhovskaia, I. S.; Matriukhina, E. A.; Ivanov, M. A.; Чугунков, Илья Владимирович; Иванов, Михаил Александрович© 2019 IEEE Pseudo-random number generators (PRNG) play an important role in the tasks of information security. Reliability and safety of information collection, processing, storage and transfer in computer systems and networks depend on PRNG's properties. As a rule, the distribution of symbols in the sequences created by generators submits to the uniform distribution law. But in some cases it is necessary that the generator created the sequences with the distribution law other than uniform. This article proposes an approach to the construction of such generators based on PRNG's. The schemes for constructing generators with a distribution law that is non-uniform are provided. At last, recommendations for estimating the properties of generators with a given distribution law are produced.
